Part 2
Analyze the data from Part 1 using Microsoft^{®} Excel^{®} software.
Write a 700 to 875word paper that includes the following information:
Describe what method you are using to compare groups.
Copy and paste the output into a Microsoft^{®} Word document, and also answer the following questions:
oWhat is the significance level of the comparison?
oWhat was the alpha level you identified in Week 3?
oWhat was the means and variance for each variable?
oWhat was the test statistic?
oWhat was the critical value for both the one and twotailed test?
oWas your test onetailed or twotailed?
oWere you able to reject the null hypothesis? In other words, did you prove there was a difference?
Talk about what these results mean in everyday language and in context to your chosen scenario.
Make a recommendation based on the findings.
Format your paper according to APA guidelines.
